My little 6” f6 newt is a winner , no coma, no vignetteing , focal length is 900mm, light weight only 6.5 kg. It’s also a great visual scope for DSO’s, Planets and moon

I’m upgrading in April to an 8” f5 newt with an EQ6- R mount to leave down at my holiday house dark site ( I will need a Baader MK 111 coma corrector though for the F5 ) more aperture and longer focal length will enable me to shoot deeper objects

Newts give clean crisp images but you need to keep mirrors clean and collimate them correctly ( no issue for me )

Hope the above information is helpful

Cheers
Martin
